Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
The inverted dustcap is integrated seamlessly with the tinted gray polypropylene
cone, for a sleek, high-tech appearance.
EPDM Rubber Surround:
The woofer is made with a one-piece EPDM rubber surround and gasket combination.
When bottom-mounting the woofer, the one-piece surround and gasket make an
air-tight seal, to prevent any loss of performance due to air leaks around the
woofer. When the woofer is top-mounted, the one-piece surround and gasket
combination enhances the overall cosmetic appearance of the woofer. EPDM has the
added benefit of being resistant to UV rays for extreme durability.
Oversized Magnet Structure:
This woofer has an oversized magnet structure, made with a 33 oz. Strontium
Four-layer Voice Coil:
A 2" four-layer voice coil is used for higher power handling.
Asymmetrical Linear Drive: This
system improves linearity and permits high output with low distortion.
Extended Vented Pole Piece: The
extended vented pole piece provides a more symmetrical magnetic field.
This woofer can provide extended bass in sealed, vented and bandpass enclosures

Recommended Sealed Box
Volume: The sealed box sizes recommended by MTX range from 0.5 cu/ft to
1.0 cu/ft. The sealed enclosure MTX highlights on their spec sheet is a 0.75
cu/ft enclosure, so this is the enclosure recommended by Crutchfield.
Box Volume: The vented box sizes recommended by MTX range from 1.0
cu/ft to 2.0 cu/ft. The vented enclosure MTX highlights on the woofer
specification sheet is a 1.5 cu/ft enclosure, so this is the enclosure
recommended by Crutchfield. One 3" diameter x 10.75" long port
should be used with a 1.5 cu/ft enclosure; a 1.5 cu/ft enclosure with a 3"x
10.75" port has a tuning frequency of 33 Hz.
Single Reflex Bandpass
Volume: The bandpass box sizes
recommended by MTX with an "S" value of 0.6 range from 0.91 cu/ft to
1.33 cu/ft. The bandpass box sizes recommended by MTX with an "S"
value of 0.7 range from 1.14 cu/ft to 1.77 cu/ft. The bandpass enclosure
MTX highlights on the woofer specification sheet is a 1.0 cu/ft enclosure with
an "S" value of 0.6, so this is the enclosure recommended by
Crutchfield. The highlighted bandpass enclosure has a sealed chamber volume of
0.39 cu/ft, a vented chamber volume of 0.53 cu/ft and a 3" diameter x 5.75"
bandpass enclosure with the higher "S" value produces a more narrow
bandwidth with better transient response; the enclosure with the lower
"S" value produces a wider bandwidth at the expense of transient
